It’s tempting to open Zillow, look up a “Zestimate,” and assume that number is what a home is worth.
“It says my house is worth $425,000—so that’s the price.”
While online estimates can be a starting point, they are far from an exact science. In fact, relying solely on them can lead to overpriced listings, unrealistic expectations, and missed opportunities.
How Zestimates Work
Zillow’s algorithm pulls data from public records, past sales, tax assessments, and comparable properties in the area. While this sounds thorough, it’s missing something huge: human insight.
What the algorithm can’t see:
The home’s current condition
Recent upgrades or renovations
Unique features or layout
Neighborhood trends or micro-market shifts
Why They Can Be Wrong
Online estimates don’t always factor in the nuances that affect value. Two homes on the same street might look identical on paper but differ greatly in upkeep, design, or appeal. Even Zillow admits its Zestimates can be off by thousands—or tens of thousands—of dollars.
For example, a home with a newly renovated kitchen and energy-efficient upgrades could sell well above the Zestimate, while another home with deferred maintenance might sell for less—even if both are listed at similar prices online.
The Real Way to Know a Home’s Value
The most accurate way to determine a property’s market value is through a comparative market analysis (CMA) done by a local real estate professional. They’ll look at:
Similar homes recently sold in the area
Current competing listings
Adjustments for condition, features, and location
The overall market trend in your neighborhood
A professional CMA combines data with local expertise, giving you a realistic price range rather than a one-size-fits-all number.
The Bottom Line
A Zestimate is a tool, not a truth. Use it as a rough starting point—but never as your sole guide for pricing or making an offer.
Thinking about selling or buying?
Skip the guesswork and get a professional market analysis based on real, current data—not just an algorithm. With the right guidance, you can price your home accurately, make competitive offers, and avoid surprises in today’s market.
